Volcano lightning glass

Volcano lightning glass spherules volcanic tektitesThe spectacle of volcano lightning may include the creation of volcano lightning glass spherules.

The lightning-induced volcanic spherules study reports finding volcanic lightning glass in a few recent volcanic eruptions, or at least proposes a mechanism for its formation.

reveal individual glass spherules ∼50 μm in average diameter that compose <5% of the examined portion of the deposit. Textures include smooth, hollow, or cracked spherules, as well as aggregates, which suggest melting of ash particles as a result of proximity to the electrical discharge channel and subsequent re-solidification of the particles into spherical morphologies. lightning-induced volcanic spherules
